Hi

The patch c5ad33184354260be6d05de57e46a5498692f6d6 on the kernel v4.1.28 
breaks the kernel. The kernel crashes when executing the boot scripts with 
"kernel panic: Out of memory and no killable processes...". The machine 
has 512MB ram and 1 core.

Note that the upstream kernel 4.7-rc4 with this patch works, but when the 
patch is backported to the 4.1 branch, it makes the system unbootable.
